Devotion & Taboo
After some noodling gods are less broken. If you go and check the gnosis document you'll see that the rules are slightly more in place. The rough idea is that any starting character can decide to be a committed worshipper of some god or another and benefit from the taboos and devotions on offer. One will lose them luck, the other will regenerate it.

Luck for the devoted is a measurement of how much the gods love you. Literally. 

Other than the obvious mess the aspects are in, there needs to be some work on distinguishing the casual worshippers from the priests. Not every Catholic can exorcise demons after all.
